DM Doodling

I can barely manage stick figures, except for that one time when I drew this one beautiful line picture, but that was it.

Normally?

Nope.

And yet … doodling and drawing ideas can genuinely lead to good things in your game.

Maps
are a great example. You can start just drawing a random map, adding in
some stuff here and there. While it most likely won’t be
publication-worthy, one aspect of it might spark an idea, and that idea
could turn into an awesome night for your players.

If you are more artistically inclined, you could draw characters and monsters, and their quirks and traits could give you ideas.
